For node to be removed "n" is it correct to simply set the "n-1.next" to "n.next"

#1

Even though it performs the desired operation is the method valid for removing elements for linked list???

public void removeAt(int index) throws Exception {

    if(index>=this.size){
        throw new Exception("INVALID INPUT");
    }

    if(index==0)    removeFirst();
    else if(index==this.size-1)  removeLast();
    else {
        getNode(index - 1).next = getNode(index).next;

        this.size--;
    }
}
